' PLOW- Specification of Letters Patent. Patented Apr 11 1916 Application'filed October 14, 1914. Serial No; 866,688.

Z '0 all whom it may concern: 1

Be it known that I, LAURENCE B. TUTEN, a citizen of the United States, residing at Orlando, in the county of Orange and State .of Florida, have invented certain new and useful Improvements in Plows, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to certain new and useful improvements in plows, and has for its object-s the production of a plow constructed entirely of steel and of light weight, insuring longevity of life and ready handling, all parts capable of prompt adjustment without the use of wrenches and adapted to be run at any angle.

With these and other objects in view, my invention consists in the novel details of construction hereinafter more particularly described and as illustrated in the drawings.

In order that those skilled in the art to which my invention appertains may know how to make and use my improved plow and to fully appreciate all of its advantages,

I will proceed to describe the same referring by numerals to the accompanying .k

drawings, in which,

Figure 1 is a side elevation of my improved plow with the share removed, but its location shown in broken lines; Fig. 2 is a top plan view with parts broken away; Fig. 3 is an enlarged top plan view of the clevis and plow beam; Fig. 4 is a section on the line a-a. of Fig. 3; Fig. 5 is a side elevation of the forward adjustable and detachable parts of the plow beam; Fig. 6 is a side elevation of means for attaching the handles; and Fig. 7 is an elevation of one of the key bolts.

Similar reference numerals indicate like parts in the several figures of the drawings.

The beam is made in two sections 1 and 2 which are pivotally connected by a transverse pivot bolt 3. The rear section 2 is formed of two spaced curved plates as clearly shown at Figs. 1 and 2, and the rear end of section 1 is formed with a series of teeth 4 (see Fig. 5) and is held in any clesired angular adjustment between the forward spaced ends of section 2 by a key bolt 5 provided with a hand nut (or cotter pin) 6, and formed with a spline 7, as shown in enlarged view at Fig. 7, and whenever key bolts are hereinafter referred to, it will be understood that they are of this particular form and that the spline 7 is the means for locking any pivoted member in adjusted position. A third or handle section 8 (see Fig. 6) of the beam is pivoted in the curved spaced ends of thesection 2 at the locality designated by 9, and theupper extremity of this section is formed with recesses 4, and is locked in adjusted positions by one of the key bolts 5, the spline 7 entering one of the recesses 4- in the same manner as the sections 1 and 2 are locked.

A full understanding of the manner in which the key bolts operate and which will apply generally when hereafter referred to, will be gathered by reference to Figs. 3 and 7, where it will be seen that the boltis formed at one end with a thread to receive the nut 6, and at the other extremity with a ring shape grip 10, and that a spiral spring 11 is employed to hold the bolt. in position with the spline 7 interlocking with one of the recesses 4, and that when the key bolt is drawn against thespring 11, a sufficient distance to withdraw the spline from the recess, the pivoted member will be free to move past the cylindrical portion of the The handles 12 are spread at their free ends as partially shown at Fig. 2, and formed at'their free ends with hand grips 13 which are held inrigid spaced relation by an ordinary tubular brace 14. These handles merge at the lower extremities and are riveted within a socket 15 extending rearwardly from the handle section 8 of the beam. The broken lines in Fig. 1 indicate the vertical adjustments of the beam and handle sections.

'- The novel. clevis secured to the forward extremity of the beam by rivets or bolts 16 is composed 'of two members, one a boxlike member 17 secured by the bolts 16, and the other member 18 pivoted at 19, in the bifurcated forward extremity of the member 17. The rear end of the member 18 is segmental and formed with teeth 4 which are engaged by the spline 7 of a key bolt as already explained and the member 18 is therefore capable of lateral adjustment indicated by the broken lines at Fig. 4 so that the line of draft may obviously be obliquely directed to the right or to the left.

18 is a whiffletree ring.

From the construction shown and described, it will be seen that a plow is produced having a large range of adjustability of its parts without the use of a tool or implement of any kind and that by means of the special devices for making the connections it may be adjusted with great celerity and the various parts folded into comparative small compass or separated for transportation or storage.

It will be seen that the construction and arrangement of my plow permits it to be readily made of steel or other like material, and of relatively few pieces; and further, the plow can be made into a right or left oblique plow in an instant by merely shifting the key 5 and rotating the clevis 18 to the desired position and releasing the key.

The plow share may be applied or removed from the plow very quickly, and when clamped in position the share cannot possibly slip.

The plow may be made of very light material, and in the actual manufacture of the plow it has been found that the plow can be made to weigh not more than 37 pounds. If the handles are broken new ones may be readily reapplied, and if any other portion of the plow is broken a new section may be easily assembled with the old.

I, of course, do not wish to be limited to any exact proportions, and many of the de-.

tails may be varied without departing from the principle ofmy invention, which resides in the general features of adjustability and connections between the parts of the plow.

What I claim as new and desire to secure by Letters Patent is 1. In a plow, a standard formed of spaced parallel bars, a handle supporting member disposed between said bars and pivotally supported at one end, a handle rigidly connected to and extending from the supporting member, and means engaging the free end of the handle supporting member and holding it in adjusted position.

2. In a plow, a standard formed of spaced parallel bars, a handle supporting member disposed between said bars and pivotally supported at one end, the free end of the handle supporting member being formed with a plurality of teeth, and a bolt passing through the parallel bars of the standard and engaging between any one of said teeth to thereby hold the supporting member in adjusted position.

- 3. In a plow, a standard formed of oppositely disposed spaced bars, a member pivotally mounted between said bars for angular movement, said member having a plurality of notches at one end, a bolt mounted in the standard for longitudinal movement, said bolt for a portion of its length having a radially projecting fin adapted to engage in any one of said notches to thereby hold the member in its adjusted position.

4. In a. device of the character described, oppositely disposed parallel elements, a member pivotally mounted between said elements for angular adjustment, said member having an arcuate toothed end, and a bolt passing through the said elements and engaging between the teeth whereby to hold the pivoted member in adjusted position.

5. In a mechanism of the character described, oppositely disposed parallel ele ments, a member pivotally mounted between said elements, said member having an arouate toothed end, a bolt mounted in said parallel elements for longitudinal move ment, said bolt for a portion of its length having a radially projecting spline adapted to engage between any two of the teeth of said pivoted member to thereby hold the member in its adjusted position, and a spring normally urging the bolt in a direction to carry its spline into engagement between the teeth.

In testimony whereof I hereunto my signature in the presence of two witnesses.
